OK, that depends on your router. If your router will let you reserve a ip address that is the way to go. Just reserve the IP address that the NET module is on now for the NET module. You will need the NET module MAC address. Once that is done choose a port for external access to the NET. I use 7092 on my Archon. Then go into you router and setup port forwarding for that port number to the NET module on port 80. Then you will need a ddns service that is supported by our router. Select that service in your router after you have your account setup at the ddns service. I have a Asus router and use their ddns service for free. Most of the services charge some kind of fee. What the ddns service does is it redirects you ddns service address to your actual internet IP address. You router will keep the ddns service updated with your current internet IP address. Unfortunately this what we have to deal with with dynamic IP addresses. It changes depending on your internet provider. Since I am not familiar with your router I may or may not be able to help with the router setup.
